PR1 — Oryza sativa Indica Group

Summary

BGIOSGA025088 (symbol PR1, also known as OiPR1) on chromosome 7 of Indica rice encodes a SCP domain-containing protein belonging to the CAP superfamily, including the V5 allergen-like and CRISP-related domains. The gene is associated with biological regulation, signal transduction, immune and defense responses to other organisms, cell death, and secondary metabolite biosynthesis, specifically diterpenoid and alkaloid anabolism. The encoded product is localized to the extracellular region and vacuole. Studies of related genes in other species, such as pathogenesis-related protein PR-1 family members, connect this family to defense signaling and stress responses.
